The ventral posterior nucleus is divided into: Ventral posterolateral nucleus, which receives sensory information from the body via the medial lemniscus, and spinothalamic tracts. Ventral posteromedial nucleus, which receives sensory information from the head and face via the trigeminal nerve.
The ventral posteromedial nucleus (VPM) is a nucleus within the ventral posterior nucleus of the thalamus and serves an analogous somatosensory relay role for the ascending trigeminothalamic tracts as its lateral neighbour the ventral posterolateral nucleus serves for dorsal column–medial lemniscus pathway 2nd-order neurons.
The ventral posterolateral nucleus (VPL) is one of the subdivisions of the ventral posterior nucleus in the ventral nuclear group of the thalamus. [1] It relays sensory information from the second-order neurons of the neospinothalamic tract and medial lemniscus (of the dorsal column-medial lemniscus pathway) which synapse with the third-order neurons in the nucleus.
The ventrobasal complex (VB) is a relay nucleus of the thalamus for nociceptive stimuli received from nociceptive nerves. The VB consists of the ventral posteromedial nucleus (VPM) and the ventral posterolateral nucleus (VPL). In some species, the ventral posterolateral nucleus, pars caudalis is also a part of the VB.

The ventral nuclear group is a collection of nuclei on the ventral side of the thalamus, it consists of the following: [1] ventral anterior nucleus; ventral lateral nucleus; ventral posterior nucleus – this is made up of two nuclei: the ventral posterolateral nucleus and the ventral posteromedial nucleus

The axons of second-order neurons ultimately synapse on neurons in the ventral posterior lateral nucleus (VPL) of the thalamus after coursing in the spinal lemniscus. After this, the 3rd order neuron fibers traverse the internal capsule and the corona radiata, ultimately synapsing in the post central gyrus (somatosensory cortex). The location ...
The ventral lateral nucleus in the thalamus forms the motor functional division in the thalamic nuclei along with the ventral anterior nucleus. The ventral lateral nucleus receives motor information from the cerebellum and the globus pallidus. Output from the ventral lateral nucleus then goes to the primary motor cortex. [1]
